efERLAcrI, or I f COIN-CONTROLLED Loox;

necessary to release the key and permit the depositor to carry it away until such time as he may replace the ykey in the lock. This type of lock is used for coin-controlled lockers or closets for the use of which a service charge is made and in which a coin must be deposited in order to releasethe key which is locked against removal when it unlocks the locker and until another coin is deposited.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings; Figure 1 is a perspective of the improved lock. Fig. 2 is a rear elevation, the parts being shown in position aslsumed whenl a coin is suspended in the lock, and the key has been withdrawn. Fig. 3 is a similar view, parts' being removed, the

mechanism being shown in position assumed when the coin has been deposited, but before the key-lock has been operated. Fig. 4 is a side elevation. Fig. 5 is a sectionl taken on.

line 5-5 of Fig. 2. Fig. 6 is a section taken on line 6-'6 of Fig. 2. Fig. 7 is a section taken on linel 7-4-7 of Figi 3. Fig. 8 is a section similar tov-F ig. 5, but showing the plates in normal posi-tion. Fig 9 is a rear view, similar toV Fig. 2, parts being removed, the locking devices for the supporting plate being shown. Fig. 10, is aperspective. of

one of the channel bars showing the manner in which it is cut away 'to receive the locking plates. Figs. 11 and'12 are details showing the operation of the presser arm for the coin.

The lock is adapted to be mounted into a channel-bar 15 which forms a part of the frame-work of the locker, the front anda. portionof one lof the sides ofthe channel- -bar being cut away to receive a plate 16 which'serves as a mount or support for the coin controlled locking mechanism. The

i specification of Lettis' Tatent. Patented Allg. 10, 1915. Application med July 16,1913. seriaiNo. 779,255. I I l lfront wall of plate 16 is provided with a pair oflugs 17 which are adapted vto fit j into the channel-bar and .hold the lower portion of the plate in position therein. A topflange 18 yis, formed on the plate and has a y slot 19 for a latch 20 which is usually secured to a reciprocable barl 21. A side flange 22 is formed on the plate and a' locking-bolt 23 for securing the locker-door 24 passes through said flange. In practice, the

lockers are usually arranged in tiers and ia common locking bolt 21 serves for an entire A vertical series or tier of locks.` At times, it is desirable 'to change the locks around or to stances, where the depositor carries off the leased. A spring strip 25'secured to the innerface of flange 22 by a rivet 27, is adapted to frictionally engage one of the Aside-i'anges of the channel-bar 15, so that when bolt 21 is voperated to release the coincont'rolled locks, the latter Awill not fall out of the channel-bar. As a result of this con.- struction, the plate 16 may be swung outwardly from the channel-bar and then lugs 17 permit it to be lifted outgof the bar. During placement or replacement of the several plates, strips 25 serve to hold each plate in position until the locking-bar 21 is operated to lock all the'plates or until the plates are removed.

i A key-lock of usual construction is secured to plate 16 by screwsV 30 and comprises a cylinder 31, a 'tumbler-barrel 32 having a key-slot 33 therein, allof which may be of usual construction. An arm 3l is secured to the tumbler-barrel and the latter is adapted to be rotated by a key 35 of the proper' with the key :and tumbler-barrel, as well understood in the art. Arm 34 extends into a notch 37 in a slidable bolt 23 which is adapted to be projected into an opening in, and to lock the locker-door 24. As usual in key-locks of 'this type, the key cannot be withdrawn from the barrel except when bolt 23 isin locking position. Besides being guided in the flange 22 of the supportingplate 16, bolt 23 is guided in a notch in a stripv 44: which is riveted, as at 45, to the back of the plate 16. Coin-controlled mecha l l substitute others therefor, and 1n some Inoperation of bolt 23.

These screws extend through arcuate slots permit the screws to pass through plate lo and to rotate with the face-plate. is formed with a stop-shoulder 4G which is adapted to engage a pin 47 which is fixed on the back of platelG and extends through a slot .48 in plate stt). rlhis stop and pin seiwe to prevent sutlieient turning of thc key 35, barrel 32 and faceplate 36 to release the key untila coin has been deposited. Stop lli is adapted to be shifted laterally by a deposited coin to clear pin'l. the plates for sutlicient movement for the Plate 3l) is provided with a forwardly turned lip 49 which is adapted to engage a deposited coin and posipast an inclined stop or cani 50 on one edge of plate al-O.

Aninclined coin-chute f is secured to the front of plate 1G so as to direct a coin downwardly and backwardly into the space 'between plates 39 and l0. The deposited coin will remain in langled 'position shown in Fig. 8, an opening 53 being cut in plate 39 to receive the lower segment of the in'-A clined coin. A spring-strip l which is secured to plate 39, as at 55, has a forwardly turned terminal 5G which is adapted to press the lower segment of the coin, after initial movement of the plates, to cause `the coin to be tilted into parallel relation with the faces of plates 39 and 40. Normally. this springarm 54 is held to clear the coin by a baclc wardly extending abutmentl 5G on plate 4l), which engages the terminal 5T of said spring-arm. y

lVlien a coin hasbeen deposited between plates 39 and l0, and key is turned, the

coin, in being forced below or past the cam 50 by lip 49, will engage the inner edge 4G of plate lleand force saidplate laterally about its pivot-screw 41, which will cause shoulder lli to clear stop-pin ll and thus release the hey-lock, so that the key can be turned into posit-ion to throw bolt '23 imo locking-position and to permit the key -)i to be withdrawn. Stop 4.0 is normally disposed to permit initial movement of plates 3f) and 4.0 and a slight turn of the key. independently of the coin. After pass above abutment 5G and will release arm 5a so that it will exert pressure upon 43 .in platelG which Plate 35T and release l initial movement of the plates, terminal 5T will the 'coin and cause it to be tilted-into para l- 1 lel relation with and against the back of plate B9 and into the path of lip 49, so that the coin will bc'positiyely shifted by said lip during rotation of key lllhen key 35 is rotatech bolt is locked and the key 235 has beenwithdrawn7 the coin will he held suspended and the parts will be in position indicated in ll`ig. 2. rThe coin will be heldbetweenedge lo of plate 39 and a holdingedge 59 on plate il). Flate 3f) is provided with a notch G5 to receive pin 47 and permit said plate to swing laterally to hold the coin. Notch (l5 is formedin edge lo onplate 39 to `permit said edge below said notch while the parts remain iiiposition shown in` Figs. Q and lVhen plates 39 and el() are restored.tonorinal position, (Fig. 3), up-

ward movement of plate 39 willfcause the edge of the notch (35 to ride'on pin. -ll'T and movet-lie holding edge of plate 39 laterally to release the coin. lllhen the lcy is replaced in the barrel, and the latteris'turned to unlock bolt Q3, plate r-ilO will bev shifted into position shown iii Fig. 3, and the coin which has been held in suspense will -be released by edges 5S) and i6. As plate 39 is moved ulnvardly, the edge of notch G5 will move plate 39 laterally away from stop-pin 4T and liolding-e ;lge 5l) to permit'the coin to .fall into a suitable receptacle. lVhen a coin is held in suspense, as shown iii Fig. 3, lip 479 on plate 239 will obstruct the passageway for the coins. so that a second coin cannot be deposited while the locker is in use.

)i coil-spring G0 has one of its terminals connectedto plate Z39 as at vGl, and its other terminal to plate all), as at G2. rThis spring serves to hold plate Bil and parts thereon normally in position to cause abutment alti fto be in alinement with stop-pin ll but perclear of the coin until after the plates have been shifted. is to leave the coin free. until manual force is applied thereto and then to apply pressure to move the upper segment of .the coin into the path of lip 49. Lostinotion of the plates is necessary to permit initial shift of the coin to release the plates. Springl G0 is applied to both of the plates :39, l() to hold them in normal position. and to restore them to such position when the liey is inserted. to release `bolt 23. By employing a'eoil-spring between the plates, both will be c'llectivcly held in normal position to insure that they'will be correctly positioned to receive a coin.

il tlat spring oli is secured to strip llland has its terminal formed vto pass into a V-shaped notch 6T in bolt rlhis formation of the notch and spring, causes the spring to aid spring G0 in imparting the to hold the coin in curved seat 5l) est .final shift to the parts in restoring themv to normal-position shown in Figs. l and 3, the

key 35 will be held against withdrawal by i the lock itself and the barrel will be 'locked against suflicient rotation to permit the key to be withdrawn by co-action to stop 46 on plate 39 and pin 47. When a. coin is depos-v ited into chute 52, it will pass into position shown in Fig. 8. If key 35`is then turned,

plates 39 and 40 will be moved in opposite directions and the initial movement will cause the coin-engaging cam 50 on one side 'of plate 40 to force the coin and plate 39 laterally, so stop 46 will clear pin 47 and permit further rotation of the key. Vhen the parts are thus released, key 35 can be rotated until the parts are in position shown in Fig. 2 and then the key can be withdrawn, bolt 23 being locked at that time. After initial movement of the plates in opposite directions, presser-arm 54 will press thelower segment ofthe coin into a flatwise position between the plates (Fig. 5.), so that the upper segment of the coin will y be firmly heldin position to be shifted by manual force applied through key 35, to operate lip 49 on plate 39 to positively shift the coin. At this time, the coin will be held suspended between edge 46 on plate 39 and edge 59 on plate 40. When the key 35 is again inserted into the lock and turned to shift the parts to normal position, the coin will be released and the device will be in readiness for another operation by a coin. Turning of the key 35 to restore the parts causes them to unlock bolt 23 and to be locked 'against operation by the key until another coin has been deposited. It also causes the plates'torelease the suspended coin as the edge of notch of plate 39 riding on pin 47 forces said plate laterally.

The invention is not to be understood as restricted to the details set forth, since these may bemodified within the scope of the appended claims without departing from the spirit and scope of the invention.
